GNPS-Heart sections from Trypanosoma cruzi-infected mice

Mice were infected with Trypanosoma cruzi strains CL, X10/4 or X10/7. Hearts were collected 12 days, 3 months and 5 months post-infection from infected mice and uninfected age-matched controlled. Hearts were divided into four sections from the base of the heart to the apex. Metabolites were extracted by a two-step protocol, first with 50% methanol (aqueous extract) then with 3:1 dichloromethane:methanol (organic extract). Liquid chromatography separation was performed on a Kinetex C8 LC Column 50 x 2.1 mm, with water+0.1% formic acid and acetonitrile+0.1% formic acid as mobile phases.
